'. INVENTOR Patented Oct. 21, 1952 UNITED STATES PATENT OFFICE FORM FOR BIOLDING CONCRETE FOOTINGS AND WALLS 4 Claims.

This invention relates to an improved structural arrangement of forms for constructing footers and vertical walls of concrete.

It is common practice when erecting concrete structures to build wood forms to the desired size'and shape. This specialized or custom building of forms is an expensive procedure and in" volves the use of numerous Wall ties which extend through the wall and must be removed at least in part after the forms are removed. The Wall ties make marks in the wall which must be patched. It is the purpose of this invention to eliminate the necessity for custom building of forms which must be dismantled after the concrete structure has set and to a large extent, waste the material used in the building forms.

It is an object of this invention to provide a structural arrangement of forms that can be assembled in most any desired relation to-obtain the efiect of custom building of forms but with standard units and particularly to eliminate the use of wall ties through the wall.

It is still another object of this invention to provide an improved structural arrangement of forms for producing concrete Wall structures wherein means are provided for attaching furring strips to the concrete wall after the forms are removed.

Further objects and advantages of this invention will become apparent from the drawings and the following description.

In the drawings:

Figure 16 is a horizontal cross-sectional view of a modified arrangement for holding together wall sections to form a corner.

Figure 17 is a cross-sectional view illustrating a manner of placing inserts in a wall section.

Referring to Figure 1, there is illustrated the form structure for providing a footer and a portion of a wall, it being understood that the footer and wall portion is poured and allowed to set before the remainder of the vertical wall is poured.

The footer forms are constructed in units of any desired length and they are adapted to be used in pairs in parallel relationship to provide an inverted T-shaped chamber in which the concrete can be poured to form a T-shaped footer and wall section as illustrated in Figure l. The footer sections l0 illustrated in Figure l at the left and right-hand sides, are identical in construction, hence only one of the sections will be described.

The footer sections I0 each consist ofa channel ll that is provided with a plurality of holes along one edge thereof to receive the spikes or rods l 2 which extend through holes and are adapted to be driven into the ground to hold the footer sections in spaced parallel relationship as illustrated in Figure l. I

A plurality of angles 13 are secured to the upper edge of channel II by any suitable means, such as the bolts l4. These angles l3 have secured to the end thereof that extends beyond the channel H a channel l5. Any suitable means may be provided for securing the angle I3 to the channel l5, such as the bolts l6a.

To set up a footer, the footer sections Ill are arranged in a spaced parallel relationship with any number of footer sections in end-to-endrelationship and the rods or spikes l2 driven into the ground to hold the footer form units in their desired position.

Before a concrete footer is poured, the inserts 16 are secured to the channel [5 by means of studs or screws or bolts to hold the inserts IS in a predetermined position within the poured concrete footer. These inserts are provided for the purpose of holding bolts that are used in assembling the vertical wall sections hereinafter described.

The inserts l6 are more clearly shown in Figure 15. The inserts consist of a cast body I! having a recess l8 therein, the face of which recess is closed by a T-shaped slot IS. A U-shaped loop extends rearwardly from the body I! of the insert [6 and is adapted to be imbedded in the concrete when the concrete surrounding it is poured, as illustrated in Figure 1. The notches 2| are provided in the insert IE to receive the bolts or studs or screws that hold the inserts to the channel l5 while the concrete is being poured.

After the footer is poured, as shown in Figure 1, the channels [0 may be removed from the channel I5 upon removal of the bolt Mia and withdrawal of the spikes or rods l2 from the ground. The channel [5 may be used as a base in cooperation with the footer upon which the vertical wall sections of the form are supported.

As illustrated in Figure 2, a plurality of channels 26 are set in edge-to-edge relationship upon the channel l5 to form a vertical form of the desired height. The channel sections 26 may all be of the-same size or their heights may be varied to meet the circumstances. The channels 26 are thereby arranged, as shown in Figure 2, to form parallel form walls resting upon the channels [5.

Vertical studs 21 are positioned on the outside of the vertically arranged wall channels 26,

each of the wall channels 26 being connected to the studs 21 by means of a hook 28 which prevents the wall channels 26 from moving inwardly.

Studs 21 are held against the channel I5 by means of bolts 29 extending outwardly of the channels I5. These bolts have the heads thereof placed within the T-shaped slot [9 of the inserts l6, and with the inserts l6 imbedded in the lower part of the footer and wall portion 25, the lower end of the wall form is prevented from outward movement relative to the footer. The upper ends of the studs 21 are connected with a tie bar 38 having a turnbuckle connection 3! which adjusts the upper ends of the bars 21 relative to one another. The studs 21 are spaced along the length of the vertical wall form at regular intervals to tie the ends together periodically and supports the channels 26.

To provide for furring strips along the vertical concrete wall 40 a plurality of pins 4| are inserted through holes in the channels 28 before the concrete wall 40 is poured.

These pins are more particularly shown in Figure 9 and consists of an elongated body 42 having a head 43 on one end thereof that is adapted to carry into the concrete wall. A protrusion is provided on the body 42 to prevent the pin from moving outwardly through. the hole and the channels 26 when the concrete is. poured. A groove 45 is provided around the pin body 42 and is adapted to receive a hair-pin tie member 46, see Figure 2, which prevents the pin 41 from moving inwardly into the wall form before the concrete is poured.

' With the wall forms arranged as shown in 4 Figure 2 and with the pins 4| in place, the concrete wall 40 can be poured.

The vertical support studs 21, as shown in Figure 2, can be channel iron or wood beams, as desired. When the concrete wall has set, it will be apparent that the form structure can be disassembled and used on another job. The inserts IE will, however, remain in the concrete 25, these being the only expendable parts.

In case a high wall is built, additional inserts 15 can be attached to the channel sections 26 as illustrated in Figure 1'7. A wood block Isa may be placed between the insert l6 and the channel 28. The wood block l6a can be removed after the wall is set so that the insert can be used to secure channel sections against the wall upon which other channel sections can be supported. After completion of use of the inserts IS, the holes left by removal of the wood blocks can be patched in the usual way.

In Figure 3 there is illustrated a modified arrangement of the vertical support bars that re tainv the channel form sections 26 in their relative positions. In this arrangement those parts which are identical with those heretofore described are provided with the same numbers and therefore perform the same functions. However, in the illustration shown in Figure 3 the studs or supports 2! are here composed of a pair of channels that are positioned in a back-to-back relationship and are held in spaced relationship by means of spacers 5| and the bolt 52, see Figure 5. The spaced relationship of the channels 50 is such as to allow the bolts 29 at the bottom part of the forms to extend betweenv the channels 50 and at the upper. end allow the tie bar 30 to extend between the channels.

The channels 26, or some of them, are provided with clamps I20 adapted. to engage one of the channels 50 for preventing moving of the wall channels inwardly of the form.

In other respects the structure illustrated in Figure 3 is identical with that illustrated in F18- ures l and 2.

In Figures 6 and 8 there is illustrated the manner of attaching furring strips to the concrete wall after the forms are disassembled. It will be understood that when the forms are disassembled, the hair-pins 46 are removed from the pins 4| to allow removal of the channels 26 from off the pins 4|. 1

A furring strip is provided with a groove 61 extending longitudinally thereof in one face and is positioned substantially midway between the longitudinal edges of the strip. A plurality of holes extend through the furring strip in alignment with the groove 6| which are adapted to receive the extending ends of the pins 4|, as viewed in Figure 6. After furring strips are placed on pins 4|, the ends of the pins are bent to lay in the groove SI and thereby clinch the furring strip to the wall 40.

The furring strips 60 are then used as the means into which nails or screws 10 can be driven to attach decorative wall sections II which may be lath and plaster or other suitable material to the furring strips and also provide a space 12 between the outer wall 40 and the inner decora tive wall I I.

In Figure 11 there is illustrated a structure for closing an end of a vertical wall section to another which may be constructed at right angles to that illustrated in Figure 11, the complete corner wall section being illustrated in Figure 12. In making the corner wall section illustrated in Fig. 12, the wall section in Figure 11 is first made and then the right angular wall attached thereto as shown in Figure 12.-

To provide for closing theend of the wall section between the parallel wall forms A and B, the end wall 15 is positioned between the adjacent faces of the channel sections 26-that form the wall sections A and B. Block s" iii are nailed or screwed to the channel sections 26 to prevent the wall 15 from moving outwardly. Angle blocks.

T! are placed along opposite edges of the wall 75 to provide a chamfer on the corners of the vertical wall 18. A wedge-shaped key block 18 is positioned along one face of the wall section B to form a wedge-shaped groove in the wall 40 when the block 18 is removed.

After the wall section is poured between the forms as arranged in Figure "11 the channel'secti'onsZS can then be arranged to form parallel form walls C and D as shownin Figure 12 with the form wall C abutting on the face of the wall ti! and the Wall sections D overlapping one edge of the wall sections '48. When the wall section 40a is poured, the recess 78a, formed in thewall section 40 will be filled by the concrete poured in the wall Mia and thereby form a key between. the two walls.

In Figure there is illustrated a form structure for pouring a corner as an integral unit. In this arrangement the channel sections forming the outer wall E are abutted with the channel sections forming the outer wall G and the channel sections H forming the near wall of the form abutted with the channel sections J at right angles thereto. Spacer blocks I03 are placed between the right angle structure I02 and the corner channel forming the corners of the walls E and G to hold these channels in positive en gagement.

With the wall sections assembled as shown in Figure 10, the corner can be formed as an integral structure.

In Figure 16 there is illustrated a modified construction for holding corner sections together. In this arrangement a bolt 95 extends between the channel sections E and G.

In Figure 13 there is illustrated an arrangement forming the walls H0 and III by separate units connected by an expansion joint I I2. In this arrangement the wall section I Il may be first poured and then by using the corner sections in Figure 10 together with other channel sections forming the other portions of the wall, the wall section H0 may be then poured. However, to provide for the expansion joint H2 between walls I I0 and HI the female dowels H3 are keyed in the wall section at the time it is poured to later receive the male dowels I [4 which key the expansion member H5. Suitable keyways can be provided on the inside face of the wall sections to provide for grooves H6 and II! to receive a caulking compound when the forms are disassembled.

In Figure 14 there is illustrated a manner of assembling wall sections l2l and I22 against apilaster E23 using the expansion joint assembly illustrated in Figure 13.

While a preferred form of this invention is illustrated, yet it will be understood that modifications that fall within the scope of the appended claims are intended to be included herein.
